Description

Technical Field

[0001] The utility model relates to the field of coal mining machines, and in particular to a dust suppression device for coal mining machines. Background Art

[0002] With the development of society and the progress of science, a large number of coal mining machines have appeared in society. Coal mining machines have evolved from coal cutting machines. Coal mining machines are a large and complex system integrating mechanical, electrical and hydraulic systems. The working environment is harsh. If a failure occurs, the entire coal mining work will be interrupted, causing huge economic losses. Coal mining machines will generate a lot of dust in the process of coal mining, so a spray device is needed for dust removal.

[0003] The prior art with patent publication (announcement) number CN211500641U discloses a high-efficiency dust reduction device for a coal mining machine, comprising a coal mining machine transmission body, a knife seat is fixedly installed on the left side of the front end of the coal mining machine transmission body, and a cutting disc is provided on the knife seat. The coal mining machine transmission body is mounted with a box body, a first through hole is opened on one side wall of the box body, and a second through hole is opened on the other side wall of the box body. The coal mining machine transmission body passes through both ends of the box body and is fixedly installed in the first through hole, a dust reduction spray device is installed in the box body, and a protective device is mounted on the outer surface of the coal mining machine transmission body, and the protective device is located in the second through hole.

[0004] The above patent document discloses a high-efficiency dust reduction device for a coal mining machine. Although it can solve the problem of the commonly used dust reduction method of using a nozzle fixedly installed on the coal mining machine to spray dust reduction, the nozzle is easily damaged when the cutting head mines coal blocks during operation. However, the disadvantage is that the nozzle is generally fixed, which makes the spraying range of the nozzle relatively limited, reducing the efficiency of dust reduction.

[0005] Therefore, we make improvements to this and propose a dust reduction device for coal mining machines. Utility Model Content
